Polyurethanes

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications.

 

Polyurethanes are used in the manufacture of high-resilience foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires (such as roller coaster, escalator, shopping cart, elevator, and skateboard wheels), automotive suspension bushings, electrical potting compounds, high performance adhesives, surface coatings and surface sealants, synthetic fibers (e.g., Spandex), carpet underlay, hard-plastic parts (e.g., for electronic instruments), condoms, and hoses.

 

Types of Polyurethanes:

Fexible Polyurethane Foam

Flexible polyurethane foams are prepared from basically the same raw materials as polyurethane elastomers. And it’s used as cushioning for a variety of consumer and commercial products, including bedding, furniture, automotive interiors, carpet underlay and packaging.

 

Rigid Polyurethane Foam

Rigid polyurethane foam includes two types of polymers such as polyurethane formulations and polyisocyanurate formulations, one of the world’s most popular, energy-efficient and versatile insulations.

 

Coatings, Adhesives, Sealants and Elastomers

The uses of polyurethanes in the coatings, adhesives, sealants and elastomers (CASE) market offer a broad and growing spectrum of applications and benefits.

 

Thermoplastic polyurethane (TPU)

Thermoplastic polyurethane (TPU) offers a myriad of physical property combinations and processing applications.

 

Reaction Injection Molding (RIM)

Car bumpers, electrical housing panels and computer and telecommunication equipment enclosures are some of the parts produced with polyurethanes using reaction injection molding (RIM).

 

Binders

Polyurethane binders are used to adhere numerous types of particles and fibers to each other.

 

Waterborne Polyurethane Dispersions (PUDs)

Waterborne polyurethane dispersions (PUDs) are coatings and adhesives that use water as the primary solvent.

 

 

Foam Density

Foam densities range from about 3 to 50 pounds/cubic foot. Depending on the foam production process, foams of the same density can differ in strength. Different manufacturing techniques demand different foam curing temperatures and chemical formulations
